October 11, 2012 The French know how to celebrate the 100th anniversary of the discovery of how cooking changes the taste, texture and color of food. Hundreds of scientists gathered recently near the village where Louis-Camille Maillard was born to honor him.
September 25, 2012 Korean researchers have found that eunuchs who worked for kings in ancient royal courts lived longer, on average, than other males who were in the inner circle. The provocative findings fit with other work that has shown an inverse link between longevity and reproduction: the greater the fertility, the shorter the life span.
September 20, 2012 Different lineages of cat with the same coloration got their looks in unique ways. The genetic variants that determine those patterns come from different mutations in the same genes. And that has some scientists thinking there may be more to the genes than meets the eye.
September 10, 2012 In a study with about 4,000 Thai schoolchildren, a vaccine for dengue fever works well against some strains of the dengue virus. But the overall level of protection was lower than hoped for. The results suggest that a vaccine for dengue fever can be developed eventually.
September 6, 2012 It's not unheard of in the animal kingdom for males to bear the brunt of early child rearing. But in one species of snail found off the coast of Baja California, many of the eggs the males lug around on their shells aren't even their own offspring.
September 5, 2012 Here's a big idea: Use a cellphone to create a cheap, simple way to diagnose heart problems in countries with no health care system. High school senior Catherine Wong won our "Joe's Big Idea" video contest by inventing a mobile ECG and building a working prototype.
August 30, 2012 Scientists have created a high-quality genome sequence of a girl who lived tens of thousands of years ago. The DNA came from a fragment of the girl's pinky bone that was found in a cave in Siberia. The new analysis gives researchers valuable new data for studying ancient human populations.
August 10, 2012 Adam Steltzner, the leader of the Mars rover's entry, descent and landing engineering team, says he was terrified of "a false positive celebration" in the control room. Fortunately for him, Curiosity landed perfectly. Now he's eyeing Jupiter's moon.
